project build and produces all files I expect (bin, hex, elf)  
but when I run:

```auto
\> ctest CMakeLists.txt
Test project D:/projects/mazelbot/libs/lib_utils/test
No tests were found!!!

```

here is my CMakeLists.txt

```auto

    set(STM32_CORE "cm7")
endif ()

add_definitions(

include(${CMAKE_CURRENT_LIST_DIR}/../../cmake/stm32.cmake)

`ctest` doesn’t look at `CMakeLists.txt` files. DId you mean to use something like `cmake /path/to/where/CMakeLists.txt/lives`?

yeh, I was thinking ctest will run tests based on CMakeLists.txt.

if I run it inside ${CMAKE\_INSTALL\_PREFIX} directory where output files are located then it works fine

lol.
